[0055] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0056] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0057] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.

[0058] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0059] This embodiment provides a container door. The container door can be used in a container. The container can be an energy storage container. The container door has a double-sealing structure, and the container door has a valve 150 disposed between the two sealing structures for drainage. Thus, when the container door is used in a container, the container has good wind and sand protection and sealing performance, making it suitable for remote areas (such as petrochemical areas, oil fields, and deserts), or for locations with harsh geological environments (such as earthquake-prone areas, flood-prone areas, etc.).

[0060] Please refer to Figures 1 to 6The container door includes a door frame 110. The door frame 110 includes posts 111, a lintel 113, and a threshold 112. There are two posts 111. When the container door is used for containers, the length of the posts 111 is parallel to the vertical direction. The two ends of the lintel 113 are connected to the tops of the two posts 111 respectively. The two ends of the threshold 112 are connected to the bottoms of the two posts 111 respectively. Thus, the door frame 110 forms a roughly rectangular frame, thereby enclosing the doorway 117.

[0061] The container door also includes a door body 120 and a hinge 170. The door body 120 is rotatably connected to a post 111 via a door pivot 160 of the hinge 170. Thus, the door body 120 can rotate between a closed position and an open position about the axis of the door pivot 160.

[0062] When the door 120 is in the closed position, the door 120 closes the doorway 117. When the door 120 is in the open position, part of the door 120 moves away from the door frame 110, thereby opening the doorway 117. At this time, the container body equipped with the container door can be entered and exited through the doorway 117.

[0063] Please refer to Figure 3 , Figures 6 to 9 As shown, the container door also includes a seal. The seal is constructed as a circumferentially closed annular structure. When the door body 120 is in the closed position, the seal is located between the door body 120 and the door frame 110 to seal the gap between the door body 120 and the door frame 110.

[0064] like Figure 8 and Figure 9 As shown, the sealing element includes a first seal 130 and a second seal 131. Both the first seal 130 and the second seal 131 are circumferentially closed annular structures. The second seal 131 is located on the inner circumference of the first seal 130. Thus, when the door 120 is in the closed position, the second seal 131 is closer to the center of the doorway 117 than the first seal 130. The second seal 131 and the first seal 130 are spaced apart. That is, the second seal 131 and the first seal 130 form concentric rings. The first seal 130 forms the outer ring, and the second seal 131 forms the inner ring. Thus, when the door 120 is in the closed position, the first seal 130 and the second seal 131 form a two-layer sealing structure, thereby increasing the sealing performance of the container door and giving the container with the door good wind and sand protection and sealing performance.

[0065] like Figure 8As shown, the container door also includes a valve 150. Valve 150 is connected to the bottom end of the door body 120. Valve 150 can be a rubber clamp valve. When the door body 120 is in the closed position, valve 150 connects the gap between the first seal 130 and the second seal 131. When valve 150 is open, valve 150 connects to the outside of the door body 120. Valve 150 is normally closed. Thus, windblown sand and rainwater from outside the container cannot enter the gap between the door body 120 and the frame through valve 150. When water is present in the gap between the first seal 130 and the second seal 131, the water can be drained from the door body 120 through valve 150.

[0066] It should be noted that the rubber clamp valve is made of rubber. The upper part of the rubber material has a first clamp valve port. The lower part of the rubber material has a second clamp valve port. The first clamp valve port connects to the gap between the first seal 130 and the second seal 131. Water within the gap between the first seal 130 and the second seal 131 can enter the rubber clamp valve through the first clamp valve port.

[0067] When the water inside the rubber clamp valve reaches a certain amount, the water, under the influence of gravity, causes the second clamp valve to open. This allows the water to flow out automatically through the second clamp valve. The gap between the first seal 130 and the second seal 131, and the closing of the second clamp valve when there is no water inside the rubber clamp valve, prevent sand and dirt from entering the rubber clamp valve through the second clamp valve and subsequently into the gap between the first seal 130 and the second seal 131.

[0068] It is understood that, in embodiments not shown, the valve can be any other existing valve, as long as it can be opened or closed for drainage.

[0069] It should be noted that when the container door is used for containers, and the door body 120 is in the closed position, along the direction perpendicular to the plane where the door body 120 is located, the side of the door body 120 away from the center of the container is the outer side of the door body 120, and the side of the door body 120 closer to the center of the container is the inner side of the door body 120. Similarly, the side of the panel 121 away from the center of the container is the outer side of the panel 121, and the side of the panel 121 closer to the center of the container is the inner side of the panel 121. The side of the door body 120 away from the center of the container is the outer side of the door body 120, and the side of the door body 120 closer to the center of the container is the inner side of the door body 120. When the container door is used for a container, and the door body 120 is in the closed position, along the direction perpendicular to the plane where the door body 120 is located, the side of the door frame 110 furthest from the center of the container body is the outer side of the door frame 110, and the side of the door frame 110 closest to the center of the container body is the inner side of the door frame 110. Similarly, the side of the frame body 118 furthest from the center of the container body is the outer side of the frame body 118, and the side of the frame body 118 closest to the center of the container body is the inner side of the frame body 118.

[0070] Please refer to Figure 8 The first seal 130 and the second seal 131 form a two-layer sealing structure, which can increase the sealing performance of the container door. When the first seal 130 fails, rainwater can enter into the gap between the first seal 130 and the second seal 131. At this time, the rainwater accumulates at the bottom of the door body 120. Thus, the rainwater can be discharged to the outside of the container through the valve 150.

[0071] In this embodiment, the container door includes a first seal 130 and a second seal 131 to form a two-layer sealing structure, thereby increasing the sealing performance of the container door and enabling the container equipped with the container door to have good wind and sand protection and sealing performance. The valve 150 is provided so that when the first seal 130 fails, water accumulated in the gap between the door body 120 and the door frame 110 can be discharged through the valve 150, preventing rainwater from entering the container body with the container door. Thus, the container equipped with the container door has good wind and sand protection and sealing performance, and can be used in remote areas and places with very harsh geological environments.

[0072] Alternatively, please refer to Figures 6 to 9 The door frame 110 is a sheet metal part. The door frame 110 has a frame body 118 and a door frame protrusion 114. Both the frame body 118 and the door frame protrusion 114 are circumferentially closed annular structures. The door frame protrusion 114 is constructed to extend outward from the frame body 118 (towards the outer side of the frame body 118).

[0073] The door body 120 is a sheet metal part. The door body 120 has a panel 121 and an inner protrusion 122. The panel 121 faces the outer side of the door body 120. The inner protrusion 122 is a circumferentially closed annular structure. The inner protrusion 122 is formed by bending and extending inward (towards the inner side of the panel 121) from the edge of the panel 121. When the door body 120 is in the closed position, the inner protrusion 122 fits onto the outer periphery of the outer protrusion 114 of the door frame to close the doorway 117.

[0074] The first seal 130 is connected to the inner protrusion 122 of the door body. When the door body 120 is in the closed position, the inner protrusion 122 presses the first seal 130 against the door frame 110. This further enhances the sealing performance of the container door.

[0075] For further information, please continue to refer to [link / reference]. Figures 6 to 9The inner protrusion 122 of the door includes a first inner protrusion wall 123 and a second inner protrusion wall 124. The edge of the panel 121 bends inward (towards the inner side of the panel 121) to form the first inner protrusion wall 123. The second inner protrusion wall 124 is connected to the end of the first inner protrusion wall 123 away from the panel 121. The second inner protrusion wall 124 extends to the outer periphery of the first inner protrusion wall 123 away from the panel 121. Thus, when the door 120 is in the closed position, the second inner protrusion wall 124 is located on the outer periphery of the first inner protrusion wall 123 away from the center of the doorway 117. Thus, the plane containing the second inner protrusion wall 124 intersects (e.g., is perpendicular to) the plane containing the first inner protrusion wall 123. The second inner protrusion wall 124 connects to a first seal 130. When the door 120 is in the closed position, the second inner protrusion wall 124 presses the first seal 130 against the door frame 110. A valve 150 is disposed on the first inner protrusion wall 123. This increases the contact area between the second inner convex wall 124 and the first seal 130, thereby increasing the sealing performance of the container door.

[0076] like Figures 6 to 9 As shown, the door frame 110 includes a frame wall 119. The door frame protrusion 114 includes a first protruding wall 115 and a second protruding wall 116. At the post 111 connected to the door pivot 160, the frame wall 119 is constructed as part of the frame 118.

[0077] At the post 111, threshold 112, and lintel 113, away from the door pivot 160, the frame wall 119 is constructed as part of the door frame protrusion 114. At this time, the frame wall 119 is attached to and connected to the frame 118.

[0078] like Figure 8 As shown, the frame wall 119 is a circumferentially closed annular structure. The door frame protrusion 114 is located on the outside of the frame 118. The inner edge of the frame wall 119 near the doorway 117 bends outward (towards the outside of the frame 118) to form a first protruding wall 115. A second protruding wall 116 is connected to the end of the first protruding wall 115 away from the frame wall 119. The second protruding wall 116 extends to the outer periphery of the first protruding wall 115 away from the doorway 117. Thus, the plane containing the first protruding wall 115 intersects (e.g., is perpendicular to) the plane containing the second protruding wall 116.

[0079] Please continue to refer to this. Figure 8 When the door 120 is in the closed position, the first inner convex wall 123 is fitted onto the first outer convex wall 115, and the first inner convex wall 123 is located on the outer peripheral side of the first outer convex wall 115 away from the center of the doorway 117. At this time, the first inner convex wall 123 and the first outer convex wall 115 are spaced apart, the second outer convex wall 116 is located within the gap between the first inner convex wall 123 and the first outer convex wall 115, and the second inner convex wall 124 is located on the outer peripheral side of the first inner convex wall 123 away from the first outer convex wall 115.

[0080] The second seal 131 is connected to the panel 121. The second outer convex wall 116 is connected to the third seal 132 (described later). When the door 120 is in the closed position, the second outer convex wall 116 presses against the second seal 131 through the third seal 132. Thus, the structure formed by the first inner convex wall 123, the first outer convex wall 115, and the second outer convex wall 116 can further increase the sealing performance of the container door.

[0081] Furthermore, such as Figure 8 As shown, the container door also includes a third seal 132. The third seal 132 is connected to the second outward convex wall 116. When the door body 120 is in the closed position, the third seal 132 abuts against the second seal 131. This further enhances the sealing performance of the container.

[0082] like Figure 6 and Figure 7 As shown, the door pivot 160 is located inside the door frame 110. Thus, the hinge 170 connecting the door body 120 and the door frame 110 is located inside the door body 120. This protects the door pivot 160.

[0083] Please refer to Figure 2 , Figure 6 and Figure 7 The container door also includes a locking assembly 180. The locking assembly 180 can be an existing locking assembly, which will not be described in detail here. The locking assembly 180 is connected to the door body 120. The bolt of the locking assembly 180 can rotate to a position connected to the door frame 110 to lock the door body 120 in the closed position. The locking assembly 180 has a keyhole 181. The keyhole 181 faces outwards from the door body 120. The locking assembly 180 also includes a key. The key can be inserted into the keyhole 181 to rotate the lock cylinder of the locking assembly 180, thereby rotating the bolt of the locking assembly 180. When the bolt rotates away from the door frame 110, the door body 120 is released from the closed position and can rotate from the open position.

[0084] like Figure 1 , Figures 3 to 7 and Figure 9 As shown, the container door also includes a protective cover 190. The protective cover 190 includes a cover portion 191 and a seat portion 192. The seat portion 192 is a circumferentially closed annular structure. The seat portion 192 surrounds the keyhole 181. The seat portion 192 is fixedly connected to the outer side of the door body 120 (i.e., the outer side of the panel 121). The cover portion 191 is movably connected to the seat portion 192. Thus, the cover portion 191 is movable between a closed position and an open position. When the cover portion 191 is in the closed position, it covers the space enclosed by the seat portion 192, thereby blocking the keyhole 181. At this time, the key cannot be inserted into the keyhole 181.

[0085] When the cover 191 is in the open position, a portion of the cover 191 separates from the base 192. At this time, the keyhole 181 is exposed, and the key can be inserted into the keyhole 181. Thus, when the cover 191 is in the closed position, rainwater and sand can be prevented from entering the keyhole 181.

[0086] Furthermore, such as Figure 4 and Figure 9 As shown, the cover portion 191 has a first protrusion 193. The seat portion 192 has a second protrusion 194. The first protrusion 193 and the second protrusion 194 are correspondingly arranged. When the cover portion 191 is in the closed position, the cover portion 191 is engaged and connected by the first protrusion 193 and the second protrusion 194. Thus, the cover portion 191 can be locked in the closed position. In addition, it facilitates operation.

[0087] Optionally, such as Figure 4 and Figure 5 As shown, the protective cover 190 also includes a flexible portion 195. The flexible portion 195 can be a thin sheet structure that can be bent and deformed. One end of the cover portion 191 is connected to the seat portion 192 via the flexible portion 195, so that it can rotate relative to the seat portion 192. Thus, the structure of the protective cover 190 is simple.

[0088] Furthermore, the cover 191, the seat 192, and the flexible part 195 are integrally formed structures.

[0089] It is understood that, in embodiments not shown, the flexible part can be fabric or a chain, etc.

[0090] like Figure 4 and Figure 5 As shown, the lower end of the seat 192 is connected to the flexible part 195. Thus, when the cover 191 is removed from the seat 192, the cover 191 naturally descends under its own weight, facilitating operation.

[0091] Furthermore, such as Figure 4 As shown, the top of the cover 191 extends into the seat 192 to form the operating part 196. This facilitates operation.

[0092] Alternatively, the protective cover 190 can be a rubber part made of rubber. As a result, the protective cover 190 is lightweight.

[0093] Alternatively, please refer to Figure 7 An elongated hole 125 is provided on the inner side of the door body 120. The major axis of the elongated hole 125 extends along the width direction of the door body 120. When the door body 120 is in the closed position, the width direction of the door body 120 is parallel to the length direction of the threshold 112. The major axis of the elongated hole 125 is the line connecting the two points of the elongated hole 125 with the largest distance between them.

[0094] Please continue to refer to this. Figure 7 The container door also includes a limiting member 140, a first limiting pivot 141, and a second limiting pivot 142. One end of the limiting member 140 is connected to the first limiting pivot 141. The other end of the limiting member 140 is connected to the second limiting pivot 142. The first limiting pivot 141 is movably inserted through an elongated hole 125. Thus, the first limiting pivot 141 can rotate within the elongated hole 125 about its axis, and can also move along the major axis of the elongated hole 125. The other end of the limiting member 140 is rotatably disposed within the container body via the second limiting pivot 142. Thus, the limiting member 140 can rotate about the axis of the second limiting pivot 142. The second limiting pivot 142 is located near a post 111 of the door frame 110 that is provided with a door pivot 160. In other words, along the length of the threshold 112, the second limiting pivot 142 is further away from the other pillar 111 relative to the pillar 111 on which the door pivot 160 is located.

[0095] like Figure 7 As shown by the dotted line, when the door 120 is in the open position, the first limiting pivot is located at the end of the elongated hole 125 near the door pivot 160, preventing the door 120 from continuing to rotate away from the closed position. This limits the opening angle of the door 120. It should be noted that the column 111 has a clearance groove for the limiting member 140. During the rotation of the door 120 from the closed position to the open position, the limiting member 140 moves into the clearance groove.

[0096] Furthermore, the door 120 rotates between the open and closed positions at an angle ranging from 110° to 130°, for example, 120°. Therefore, the door 120 has a large opening angle.

[0097] This utility model also provides a container. The container includes the aforementioned container door.

[0098] In this embodiment, the container includes the aforementioned container door, which includes a first seal 130 and a second seal 131 to form a two-layer sealing structure, thereby increasing the sealing performance of the container door and enabling the container with the container door to have good wind and sand protection and sealing performance. The valve 150 is provided so that when the first seal 130 fails, water accumulated in the gap between the door body 120 and the door frame 110 can be discharged through the valve 150, preventing rainwater from entering the container with the container door. Thus, the container with the container door has good wind and sand protection and sealing performance, and can be used in remote areas and places with very harsh geological environments.
